The specific embodiment

Figure 1A to Fig. 5 represents the lever-arch file folder mechanism according to the utility model first embodiment, and this lever-arch file folder mechanism is represented with 100 usually.Described mechanism 100 comprises the base 102 that can be made by metallic plate.Two posts 104 are firmly fixed at 102, two arched members 106 of base and are cooperated by a pair of anchor clamps 108 near base 102, thereby arched member 106 can rotate around axis T-T pivot with respect to base 102 and post 104.Arched member 106 is connected to each other by crank section 110, and described crank section 110 is fixed in arched member 106 and forms with arched member 106 integral body, to be synchronized with the movement.By such setting, can make the rotation of crank section 110 pivots, thereby produce the synchronous pivoting movement of arched member 106 between the primary importance and the second place, in described primary importance, the free end of the free end of arched member 106 and post 104 closely cooperate (as Figure 1A to shown in Figure 5), to form two from base 102 upwardly extending rings (" ring seal state "), be used to keep being installed with the paper in hole, in the described second place, the free end of arched member 106 breaks away from the free end of post 104 and cooperates, thereby open two rings (" ring open mode "), take out or insert post 104 and/or the arched member 106 from post 104 and/or arched member 106 with the paper that allows to be installed with the hole.

Be leaf spring 112 below the crank section 110, described leaf spring 112 acts on crank section 110 from bottom to top.By such setting, leaf spring 112 makes arched member 106 away from the rotation of post 104 pivots by crank section 110 bias voltage arched members 106, and promptly pivot rotates to the ring open mode.Metallic plate 114 extends upward from base 102 substantially.Metallic plate 114 and base 102 whole formation for example, can be formed by same metallic plate stamped with base 102.

Lever-arch file folder mechanism 100 comprises Control Component, and this Control Component is represented with 116 usually, shown in Fig. 6 A to Fig. 6 E.Described Control Component 116 comprises the lever 118 that is connected with wheel 120 by pawl and ratchet device.Wheel 120 can be made by metal or plastics.Lever 118 has motion arm 118a, is fixed with mat 118b at the free end of motion arm 118a by the mode as molding, and described mat 118b can be made by softer materials such as plastics, is used for further providing the comfortableness of use.

Torsion spring 122 cooperates with lever 118 by rivet 124.By Fig. 2 A to Fig. 3 as can be known, the underarm of torsion spring 122 cooperates with plate 114, and the upper arm of torsion spring 122 cooperates with the hook 126 of lever 118, and described hook 126 extends to a side of lever 118.By such setting, lever 118 by torsion spring 122 and away from base 102 towards the upper position bias voltage, as Figure 1A to shown in Figure 5.

Wheel 120 firmly fixes with ratchet 130 by two pins 128 and is connected, to be synchronized with the movement.Wheel 120 cooperates with lever 118 by torsion spring 132 and rivet 134 with ratchet 130 and pin 128.When Control Component 116 was installed on lever-arch file folder mechanism 100, the upper arm of torsion spring 132 cooperated with the hook 136 that extends to these lever 118 another sides of lever 118.The underarm of torsion spring 132 is fixing with respect to plate 114.For example, platelet can slave plate 114 stamps out and substantially vertically towards pawl and ratchet device bending.Aperture can pass described platelet, and the lower end of torsion spring 132 can fixedly hold by described aperture.The upper arm of torsion spring 132 is used as " pawl " in pawl and ratchet device.The upper arm of torsion spring 132 usually cooperates with the straight edge 138 of the tooth 140 of ratchet 130.By such setting, the upper arm of the upper arm of wheel 120, ratchet 130, pin 128, rivet 134, torsion spring 132, lever 118, torsion spring 122 and rivet 124 can both be around common rotation of axis P-P pivot or rotations.The straight edge 138 of the tooth 140 of ratchet 130 P-P that parallels to the axis can tilt with respect to axis P-P though be to be understood that straight edge 138.

Wheel 120 comprises cover plate 141, on the first type surface of pawl and ratchet device, be fixed with cam 142 at cover plate 141, described cam 142 has waveform periphery cam face 144, on waveform periphery cam face 144 each other alternately and equal angles be provided with five protuberances 146 and five depressed parts 148.

As Figure 1A to the ring seal state shown in Figure 5, a protuberance 146 compresses and acts on the portion that projects upwards of crank section 110.When lever 118 away from as Figure 1A to shown in Figure 5 normal when stablizing upper position, i.e. being directed downwards pivot when rotation shown in the arrow A in Fig. 2 A, because the upper arm of torsion spring 132 cooperates with the straight edge 138 of the tooth 140 of ratchet 130, ratchet 130 will rotate along the direction identical with the downward pivoting movement direction of lever 118 synchronously around axis P-P.

When lever 118 overcomes the biasing force of torsion spring 122 and when moving to Fig. 7 A to lower position shown in Figure 11, the wheel 120 that has cam 142 arrives a position, in this position, the depressed part 148 of cam face 144 is towards the portion that projects upwards of crank section 110, thereby leaf spring 112 is rotated to head lamp brush guard pivot, so that arched member 106 is away from post 104 pivots rotations, thereby open describedly to ring, and for example Fig. 7 A is to shown in Figure 11.Distance between the lower position of lever 118 and the base 102 is less than the upper position of lever 118 and the distance between the base 102.Each pivoting movement downwards of lever 118 makes cam 142 rotations 36 degree.

When lever 118 occupied this lower position, lever 118 was in unstable position.When discharging downward active force (for example being applied by the user), lever 118 will turn back to as Figure 12 A to the normal settling position in its top shown in Figure 16.This upwards return movement of lever 118 can not change described state to ring.Specifically, when lever 118 when turning back to as Figure 12 A to position, its underpart shown in Figure 11 as Fig. 7 A to its upper position shown in Figure 16, described to ring retaining ring open mode.

By upwards the returning in the pivoting movement process of the lever that return action produced 118 of torsion spring 122, the upper arm of torsion spring 132 slides along the beveled edge 150 of the adjacent teeth 140 of ratchet 130, up to cooperating with the straight edge 138 of adjacent teeth 140.Because with respect to the corresponding sports of crank section 110, arched member 106 can not rotate with respect to post 104 pivots wheel 120 (thereby cams 142), thereby can not cause described any variation to ring status.

Figure 17 A represents when lever 118 is in position, its underpart, and cooperating between the upper arm of torsion spring 132 and the ratchet 130, Figure 17 B represents when lever 118 is in its upper position, cooperating between the upper arm of torsion spring 132 and the ratchet 130.

When mechanism 100 is in when Figure 12 A is to the state shown in Figure 16, lever 118 can rotate to lower position by downward once more pivot, thereby produce 120 (comprising cover plate 141 and cam 142) of wheel along with lever 118 move downward rotatablely moving synchronously of the identical direction of direction, the contiguous protuberance 146 of cam 142 is cooperated with the portion of extending upward of crank section 110, thereby pivot rotation arched member 106, arched member 106 and post 104 are closely cooperated, thereby seal described ring.

When therefore lever 118 was in position, its underpart, lever 118 can turn back to its upper position under the partial pressure of torsion spring 122.Lever 118 along with Fig. 2 A in the upwards pivoting movement process in the opposite direction of the side shown in the arrow A, the upper arm of torsion spring 132 slides along the beveled edge 150 of the adjacent teeth 140 of ratchet 130, up to cooperating with the horizontal straight edge 138 of adjacent teeth 140.Thereby mechanism 100 returns to as Figure 1A to ring seal state shown in Figure 5.In addition, the upwards return movement of lever 118 can not bring described any change to ring status.

By top narration as can be known, mechanism 100 of the present utility model has following distinguishing characteristics at least:

A. only at lever 118 during along a direction pivoting movement, in the present embodiment, this pivoting movement be lever 118 from it the portion position to the downward pivoting movement of position, its underpart, described to the ring just can change its state, no matter be to the ring open mode, still from encircling open mode to the ring seal state from the ring seal state;

B. lever 118 from position, its underpart to its normally stablize upper position upwards return pivoting movement the time, described state to ring does not change;

C. at lever 118 from upper position during to the downward pivoting movement of lower position, wheel 120 is only along same direction rotation, will described ring being moved to the ring open mode from the ring seal state, and moves to the ring seal state from encircling open mode;

D. when mechanism 100 is in its ring seal state, first protuberance 146 contact of cam 142, in abutting connection with and act on the portion that projects upwards of crank section 110, and move through the ring open mode when mechanism 100, when recovering the ring seal state, second protuberance 146 contact of cam 142, in abutting connection with and act on the portion that projects upwards of crank section 110, or the like.By such setting, can prolong the service life of mechanism 100, all given a plurality of protuberances 146 because act on the friction of the portion that projects upwards of crank section 110;

E. when mechanism 100 was in its ring open mode and lever 118 and is in its upper position (as Figure 12 A to shown in Figure 16), the paper that enough spaces allow to be installed with the hole inserted in post 104 and the arched member 106, or takes out from post 104 and arched member 106; And

F. Control Component 116 will be taken turns 120 rotatablely move and convert moving up and down of leaf spring 112 to.

In said mechanism 100, described only when lever 118 when the portion position is to the downward pivoting movement in position, its underpart from it to ring change state, no matter be from the ring seal state to the ring open mode, still from the ring open mode to the ring seal state.But should be understood that, by the tooth 140 of ratchet 130 is located in the other direction, and by torsion spring 122,132 is suitably reorientated, lever 118 can be by towards the lower position bias voltage, only when lever 118 from position, its underpart when its upper position makes progress pivoting movement, described to the ring just can change state.

Figure 18 A to Figure 22 represents the various views according to the lever-arch file folder mechanism of the utility model second embodiment, and this lever-arch file folder mechanism is represented with 200 usually.Mechanism 200 structurally is very similar to said mechanism 100.The lever 218 of Control Component 216 can from as Figure 18 A to its upper position shown in Figure 22 downwards (i.e. the direction shown in the arrow B along Figure 19 A) rotate towards base 202 pivots, so that (wherein a coupled columns 204 closely cooperates with a pair of arched member 206 from the ring seal state with mechanism 200, to form the ring of a pair of sealing) (its center pillar 204 pivots rotate to change to the ring open mode, cooperate with arched member 206 disengagings), extremely shown in Figure 28 as Figure 24 A.

Except lever 218, Control Component 216 comprises the wheel 220 that can be operatively connected by pawl and ratchet device and lever 218.Wheel 220 comprises the cover plate 241 with cam 242 secure fit (for example by integrally formed mode).The ratchet 230 of pawl and ratchet device is fixed firmly to wheel 220 by two pins 228, to be synchronized with the movement.The torsion spring 232 that constitutes " pawl " in pawl and the ratchet device is supported by rivet 234 between lever 218 and ratchet 230.Cam 242 has waveform cam face 244, on this waveform cam face 244 each other alternately and equal angles be provided with five protuberances 246 and five depressed parts 248.Another torsion spring 222 cooperates with lever 218 by rivet 224.The upper arm of the upper arm of wheel 220, ratchet 230, rivet 234, torsion spring 232, lever 218, torsion spring 222 and rivet 224 can both be around common rotation of axis R-R pivot or rotations.

By comparison diagram 6E and Figure 23 E as can be seen, the main distinction between the Control Component 116 of mechanism 100 and the Control Component 216 of mechanism 200 is that the underarm of torsion spring 222 is shorter than the underarm of torsion spring 122.In mechanism 100, the underarm of torsion spring 122 cooperates with the plate 114 of close base 102.Yet in mechanism 200, as Figure 19 A and shown in Figure 20, the underarm of torsion spring 222 cooperates with the plate 214 of base 202 further away from each other.

When mechanism 200 is in the ring open mode, when lever 218 is in position, its underpart, extremely shown in Figure 28 as Figure 24 A, if release action is in the downward active force of lever 218, then lever 218 will turn back to its stable upper position under the effect of the upwards biasing force of torsion spring 222 upper arm, do not change simultaneously described state to ring, extremely shown in Figure 33 as Figure 29 A.

Then, can be once more pivot rotating lever 218 downwards, described to seal to ring.When release action during in the downward active force of lever 218, lever 218 will turn back to its stable upper position under the effect of the upwards biasing force of torsion spring 222 upper arm, can not change described state to ring simultaneously.Then, mechanism 200 will recover its as Figure 18 A to state shown in Figure 22.

Lever-arch file folder mechanism such as Figure 34 A according to the utility model the 3rd embodiment are extremely shown in Figure 38, and this lever-arch file folder mechanism is represented with 300 usually.Figure 34 A to Figure 38 represents to be in the mechanism 300 in the ring seal state.Similar with said mechanism 100,200, mechanism 300 comprises the base 302 that can be made by metallic plate.Two posts 304 are firmly fixed at 302, two arched members 306 of base and cooperate with base 302, are used for relative pivoting movement.Arched member 306 is interconnected with one another by crank section 310, and crank section 310 is fixed in arched member 306 and forms with arched member 306 integral body, to be synchronized with the movement.By such setting, can make the rotation of crank section 310 pivots, thereby produce the synchronous pivoting movement of arched member 306 between the primary importance and the second place, in primary importance, the free end of the free end of arched member 306 and post 304 closely cooperate (as Figure 34 A to shown in Figure 38), to form from base 302 upwardly extending two rings (" ring seal state "), be used to keep being installed with the paper in hole, in the second place, the free end of arched member 306 breaks away from the free end of post 304 and cooperates, thereby open described two rings (" ring open mode "), from post 304 and/or arched member 306, take out or insert in post 304 and/or the arched member 306 with the paper that allows to be installed with the hole.

Be leaf spring 312 below the crank section 310, described leaf spring 312 acts on crank section 310 from bottom to top.By such setting, leaf spring 312 away from post 304, promptly is biased into the ring open mode by crank section 310 bias voltage arched members 306.Metallic plate 314 extends upward from base 302 substantially.Metallic plate 314 and base 302 whole formation, and for example, can form by same metallic plate stamped with base 302.

Lever-arch file folder mechanism 300 comprises Control Component, and this Control Component is represented with 316 usually, and is extremely shown in Figure 40 as Figure 39 A.Control Component 316 comprises the lever 318 that is connected with wheel 320 by pawl and ratchet device.Describedly take turns 320 and comprise the cover plate 341 and the cam 342 of secure fit each other, for example be integral with each other by a working of plastics.For purpose clearly, cover plate 341 only is represented by dotted lines in Figure 34 B, Figure 35 A and Figure 39 A, and does not represent in Figure 34 C to Figure 34 E, Figure 35 B, Figure 36, Figure 38 and Figure 39 B to Figure 39 F.

To shown in Figure 40, in Control Component 316, take turns 320 (comprising cover plate 341 and cam 342) and ratchet 330 secure fit (for example, forming) as Figure 39 A by integral body.Lever 318 cooperates with ratchet 330 by rivet 334.Pawl 352 cooperates with torsion spring 332, lever 318 by rivet 354, thereby pawl 352 can rotate about lever 318 pivots around axis S-S.When suitable assembling, torsion spring 332 is towards the tooth 340 bias voltage pawls 352 of ratchet 330, and shown in Figure 39 C and Figure 39 E, the free end of its median claw 352 cooperates with the tooth 340 of ratchet 330.Torsion spring 322 cooperates with lever 318 by rivet 324.By such setting, the upper arm 356 of wheel 320 (and cam 342 and ratchets 330), lever 318 and torsion spring 322 can be around common axis M-M rotation or pivot rotation.

As Figure 35 A, Figure 37 and shown in Figure 38, plate 314 secure fit of the underarm of torsion spring 322 and mechanism 300, the upper arm of torsion spring 322 cooperates with lever 318.Thereby, torsion spring 322 towards as Figure 34 A to upper position bias voltage lever 318 shown in Figure 38.

Described cam 342 has periphery waveform cam face 344, has on this waveform cam face 344 relative to each other alternately and six protuberances 346 and six depressed parts 348 of equal angles setting.When mechanism 300 is in Figure 34 A to the ring seal state shown in Figure 38 the time, a protuberance 346 cooperates and acts on this with the portion of projecting upwards of crank section 310 and projects upwards portion, thus the relation of closely cooperating of maintenance arched member 306 and post 304.

When the lever 318 of mechanism 300 in Figure 35 A shown in the arrow C be directed downwards the pivot rotation time, pawl 352 moves downward around axis M-M.Because cooperating between the tooth 340 of pawl 352 and ratchet 330, moving downward of pawl 352 will make ratchet 330 (thereby cam 342 and cover plate 341) rotate along the direction identical with the direction of motion of lever 318 around axis M-M.Each pivoting movement downwards of lever 318 can make cam 342 rotations 30 degree.

When therefore rotation of wheel 320, and lever 318 is when being in the bottom, and to shown in Figure 45, depressed part 348 is towards the portion that projects upwards of crank section 310 (as Figure 41 B and shown in Figure 45, wherein for purpose clearly, removing cover plate 341) as Figure 41 A.Thereby leaf spring 312 can rotate to head lamp brush guard pivot, with pivot rotary crank part 310, thereby makes arched member 306 away from the rotation of post 304 pivots, thereby opens described ring.

When release action during in the downward active force of lever 318, because the upwards biasing force that the upper arm 356 of torsion spring 322 is applied, lever 318 will turn back to upper position, and not change the state of mechanism 300, cooperate with the adjacent teeth 340 of ratchet 330 up to pawl 352, extremely shown in Figure 48 as Figure 46.

Figure 49 represents lever 318 from position, its underpart (LP), through centre position (IP), to the moving process of its upper position (UP).When lever 318 was in position, its underpart (LP), pawl 352 cooperated with the tooth 340 of ratchet 330.In the upwards return movement process of lever 318, pawl 352 slides along the outside of the adjacent teeth 340 of ratchet 330, by position (IP) in the middle of it, arrives its upper position (UP) up to lever 318, at this upper position, pawl 352 cooperates with the adjacent teeth 340 of ratchet 330.In this motion process, wheel 320 (thereby ratchets 330) do not carry out any rotatablely moving with respect to base 302, thereby can not change described state to ring.

When mechanism 300 is in when Figure 46 is to the state shown in Figure 48, can be once more pivot rotating lever 318 downwards, with rotating cam 342, thereby act on crank section 310, so that encircle 306 pivots rotations, be back to post 304 and closely cooperate, thereby seal described ring.Then can trip lever 318, make it turn back to its upper position, and do not change the state of described ring.

In mechanism 300, torsion spring 322 is arranged between pawl 352 and the lever 318, so that necessary preparation load to be provided.As selection, shown in Figure 50 A to Figure 50 C, lever 318 can alternatively be connected with pawl 352 by stretching spring 358, and described stretching, extension spring 358 also is used for towards ratchet 330 bias voltage pawls 352.

Figure 51 A to Figure 53 has represented that lever 418 is in the lever-arch file folder mechanism according to the utility model the 4th embodiment that is in the ring open mode of upper position, and this lever-arch file folder mechanism is represented with 400 usually.

The structure of the structure of mechanism 400 and said mechanism 100,200,300 is similar, the main distinction is the structure (referring to Figure 62 A to Figure 62 E) of Control Component 416, and Control Component 416 is used to operate opening and sealing of a pair of ring that formed by two posts 404 and two arched members 406.

More clearly shown in Figure 62 A to Figure 62 E, lever 418 cooperates with the ratchet 430 of pawl and ratchet device by connecting rod 460,462, thereby lever 418 can be with respect to the rotation of connecting rod 460 pivots, and connecting rod 460 can rotate with respect to connecting rod 462 pivots.Connecting rod 462 also cooperates with pawl 452 pivots, and described pawl 452 is stretched tooth 440 bias voltages of spring 458 towards ratchet 430.Connecting rod 462 is fixedlyed connected with ratchet 430, and ratchet 430 is fixedlyed connected or whole formation with the wheel 420 with cam 442 again.Cam 442 has relative to each other alternately and four protuberances 446 and four depressed parts 448 of equal angles setting.

When mechanism 400 was in the ring open mode shown in Figure 51 A to Figure 53, the portion of projecting upwards of crank section 410 was contained in the depressed part 448 of cam 442.Because the upwards biasing force of leaf spring 412, the arched member 406 that connects by crank section 410 rotates away from post 404 (described post 404 is fixed in base 402) pivot, thereby mechanism 400 is remained in its ring open mode.

When lever 418 when (shown in arrow D among Figure 54 B) pivot rotates to lower position shown in Figure 54 A to Figure 57 downwards around axis F-F (referring to Figure 56), because the cooperation between pawl 452 and the ratchet 430, make the rotation of the direction shown in the arrow E in Figure 54 B of ratchet 430 and cam 442, this direction is opposite with the pivot direction of rotation of lever 418.This makes a protuberance 446 of cam 442 cooperate with the portion of projecting upwards of crank section 410, thereby makes the rotation of arched member 406 orientation columns 404 pivots, till post 404 and arched member 406 closely cooperate each other, thereby seals described to ring.

Lever 418 also cooperates with torsion spring 422 towards upper position bias voltage lever 418.Thereby when the release user acts on the active force of lever 418, lever 418 will turn back to the normal settling position in top under the partial pressure of torsion spring 422, shown in Figure 58 A to Figure 61, and not change described state to ring.Owing to stretch the biasing force of spring 458, pawl 452 will slide along the outside sweep surface of ratchet 430, cooperate with adjacent teeth 440 up to pawl 452, shown in Figure 58 B and Figure 60.

Shown in Figure 63 A to Figure 63 C is clear, when lever 418 when portion position (shown in Figure 63 A) rotates to position, its underpart (shown in Figure 63 C) through centre position (shown in Figure 63 B) pivot downwards from it, make ratchet 430 rotations 45 spend, thereby also make cam 442 rotations 45 degree.When trip lever 418 subsequently, lever 418 will turn back to its upper position (shown in Figure 64 A to Figure 64 C), and pawl 452 will move to adjacent teeth 440 from its tooth that cooperated at that time 440, to cooperate with adjacent teeth 440.

As can be seen, lever 418 can be around fixing axis F-F pivot rotation, connecting rod 462, ratchet 430, cam 442 and take turns 420 fixed axis G-G (referring to Figure 53) the pivots rotations that can be centered around the axis F-F top and the F-F that parallels to the axis.Pawl 452 can center on the rotation of axis H-H (referring to Figure 62 E) pivot, and described axis H-H is also parallel with axis F-F, but can move when lever 418 motions.

When mechanism 400 is in the ring seal state shown in Figure 58 A to Figure 61, can make lever 418 from (direction shown in the arrow D along Figure 54 B) the pivot rotation downwards of its normal upper stable position, next depressed part 448 with translating cam 442, make its portion that projects upwards towards crank section 410, thereby allow arched member 406 away from the rotation of post 404 pivots, thereby open described ring.When release action during in the downward active force of lever 418, lever 418 will turn back to its top and stablize the normal position under the effect of the upwards biasing force of spring 422, and can not change the state of mechanism 400.

In the said mechanism 100,200,300 and 400 each can be for example fixedlyed connected with substrate such as cover plate by rivet etc., and to form lever-arch file folder, described substrate can be made by cardboard, plastics etc.

It should be understood that the embodiment that the utility model can be implemented above only exemplarily has been described, under the prerequisite that does not depart from spirit of the present utility model, can carry out various modifications and/or replacement it.

Should also be understood that some feature of the present utility model that in the context of different embodiments, describes for clarity, can be in conjunction with in one embodiment.On the contrary, for brevity and the of the present utility model a plurality of features that in the context of an embodiment, illustrate, also can provide respectively or provide in the mode of any suitable time combination.
